Title: Improvements in and relating to the production of hydrocarbon motor fuels
IPC: C10G55/04
Filed: 1934-01-11
Abstract: <PICT:0423324/III/1> Motor fuels are prepared from hydrocarbon distillates, obtained by a cracking process, by subjecting the vaporized distillate to a fractional condensation so as to obtain a light and a heavy distillate, these being subjected respectively to purification with an adsorptive material and an acid after which they are mixed to produce a fuel having a high anti-knock value.  As shown, vapours from a vapourphase cracking plant pass into a fractionating tower 1 by a pipe 2, the light ends, boiling point 40 to 180 DEG  C., passing off by a pipe 30 to a condenser 31, and the heavy ends, boiling from 150 to 230 DEG  C., passing by a pipe 6, a condenser 7 and a pipe 8 to an acid treating vessel 9.  By a pipe 12 the oil passes to a centrifugal separator 14 and thence to a clay treating vessel 16 and a filter 18.  From the filter it may pass to a pipe 28 by a pipe 29 or to a re-run still 22 and an evaporator 23 from which the heavy ends pass away by a pipe 24 and vapours pass to a condenser 25 and a receiver 26, a pump 27 forcing it to the pipe 28 to which also the purified light distillate is conveyed by a pipe 66. The light distillate is made up from uncondensed vapours and gases which are conveyed from the column 1 by a pipe 30 to a condenser 31 and thence to a separator 33 whence part is returned by a pipe 37 to the column 1 and the remainder leaves by a pipe 38.  Uncondensed vapours and gases pass from the separator 33 by a pipe 34 to a compressor 39, a cooler 40 and a separator 41 whereby a fraction boiling between 30 and 120 DEG  C., is fed to the pipe 38 to be combined in a pipe 43 with the light distillate from the separator 33.  Gases from the separator 41 pass to a caustic washing tower 45 after which they are compressed by a pump 48 and polymerized in a furnace 49 and a reaction coil 50 from which the vapours are separated and delivered to a cooler 56 and a receiver 57 whence the condensate passes to the pipe 43.  The combined light distillates then pass to the clay treatment where they may be vaporized in a furnace 63 and pass to the clay treating vessel 64.  From the vessel 64, the light distillates are conveyed by the pipe 66 to be combined in a pipe 67 with the heavy distillate from the pipe 28.  Final traces of acid are removed by treatment with an alkali wash in a contactor 68 whence the blended distillates are conveyed by a pipe 71 to a mixing chamber 73 where the distillates may be combined with a gum inhibitor from a reservoir 76.  If desired the distillates may also be combined in the mixer 73 with straight run gasoline from a tank 78.

Title: Appliance for inhaling apparatus, particularly for analgesia and narcosis
IPC: F16K31/126
Filed: 1946-01-12
Abstract: 629,159. Inhaling appliances. WARMING, A. Jan. 12, 1946, No. 1166. Convention date, May 10, 1944. [Class 81 (ii)] [Also in Group XXIX] An appliance for inhaling apparatus, particularly for analgesia and narcosis, in which a mixture of two or more gases is delivered, one of said gases being oxygen, characterised in that the supply line for one or more of the gases comprises a cut-off device controlled directly or indirectly by the pressure of the oxygen applied in such a manner that the said cut-off device is not opened unless oxygen is available for delivery, has the cutoff device provided with (a) means for applying a force tending to open the device and created by the pressure of the oxygen within the device, (b) means for applying a force tending to close the device and created by the pressure of the other gas, (c) Means for applying a mechanical force tending to close the device and equal to or greater than the friction therein, e.g., a spring. As shown, oxygen is led through a line 10 to a pressure reducing valve 12 of known type containing a diaphragm 16 connected to a valve body 18 and actuated by a compression spring 14 and screw 20. Nitrous oxide is supplied through a line 24 to a second valve 26 having a diaphragm 30 in contact with a tension spring 28, screwed in a yoke 32 suspended from a screw 34. Oxygen from the valve 12 passes along the lines 40 and 42 to the space 38 in the valve 26 where it depresses the diaphragm 30, which in turn lifts the valve body 36 from its seat to permit nitrous oxide to pass into the space 44 of the valve 26. The nitrous oxide passes through the aperture 50 into a collecting chamber 46, where it mixes with oxygen from the line 40, which has passed the aperture 48. The size of the apertures 48 and 50 is such as to give the mixtures of oxygen and nitrous oxide collecting in 46 the desired proportions. These proportions may be varied by inserting adjustable needle valves in the apertures 48 and 50. The total gas mixture delivered may be regulated by the screw 20 or by a throttle valve (not shown) in the collecting piece 46. Two or more gases in addition to oxy. gen may be delivered in apparatus in which valves similar to valve 26 are inserted in the supply line of the other gases, said valves each being controlled by the pressure of the oxygen as above. Alternatively, the oxygen pressure may control the supply of one gas, which in turn may control the supply of a third. In a modification, the valves are arranged so that the gas delivered is dependent upon both the oxygen and nitrous oxide being supplied. Specifications 199,300, [Class 86], and 562,127 are referred to.
